 Affects the size of the generated hash table.  The numeric argument for
 this option indicates ``how many times larger or smaller'' the maximum
 associated value range should be, in relationship to the number of keywords.
-If the @var{size-multiple} is negative the maximum associated value is
-calculated by @emph{dividing} the number of keywords by it.  For
-example, a value of 3 means ``allow the maximum associated value to be
-about 3 times larger than the number of input keywords''.

-Conversely, a value of -3 means ``allow the maximum associated value to
-be about 3 times smaller than the number of input keywords''.  Negative
-values are useful for limiting the overall size of the generated hash

-values.
